Application filed October 10,1906` Serial No. 338,215.

To all whom it may concern:

Be it ltnow'n that I, ALONZO E. SMi'rH, a citizen of the United States, residing at the borough of Brooklyn, city oi New York, county of Kings, and State of New York, have invented certain new and useful Improves ments in Compound Railway-Rails, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings and the referenco characters marked thereon.

rl`his invention has relation to railway rails composed ol a base or bed portion and atop or tread portion united to form a completed rail. i

The object ol my invention is to provide or produce a compound rail which shall be capable of being easily and cheaply constructed and assembled for use, formingl a practically continurnis'rail, whereof the ends of the sections are cut square so that they will abut against cach other` after the manner of ordinary railway rail sections, wherein the two sections are uniformly supported and united with respect to cach other7 whereof the upper or tread sections may be removed and interchangcd or replaced by others and wherein the tread sections may be cut to remove any portions thereof 'and the same replaced by other portions without interioring with the stability ol' the entire rail.

To accomplish all ol the lori-going object and to secure other and further advantages in thc matters o construction,emplacement, operation and repairs, my improvements involve certain new and useful peculiari tics ol' construction and relative arrangements or combinations of parts, as will bc herein iirst 'fully described and then pointed out in the claim.

ln the accompaflying drawings which form part" oi' his specification, Figure l isa side View of a portion ol a compound continuous rail constructed and arranged l'or operation in accordance with my invention and involving my improvements. Fig. 2' is a perspective view showing the end of one of the base'sections with a tread section in place therewith but cut across near the end of the base section. Fig'. 3 is a cross section and elevation upon a plane at right angles with the tread oi the rail and through one ol the tie bolts showing au electrical coupling piece or conductor in dotted lines.

ln all these iigures like letters ol reference, wherever they occur, indicate corresponding parts.

A, A, are the hase sections or pieces of the rail, the same being intended to be secured upon the ties ol the road bed according to any ol` the approved manners of sccurinpr rails. The ends ol these sections are cut square across. as at o, o, so that these ends will abut' against cach other when the rail is laid down and so that the rail may bo built in position without dilliculty. 'lhc base ilaugc ol this buse scr-tion is ol the usual width and thc two webs rising,r therefrom, represented at h, b, are scl'iaralcd by a space which gradually increases in width, l'rorn thi` bottoni to Ihc top, and .this space is in- 4unnecessary additional cost.

tended to receive the tongue or flange with which the tread section is supplied. The outer surfaces of the' Webs b, b, are substantially parallel and the tops of these webs are flat so as to form plain Ilat bearings for the upper part of the tread section. tween the upper parts oi the inner `iaces oi the webs b, o, is about twice the width of the top of oneoi the webs to properly distribute the strengthvof.thelmaterial of which the rail is made, but these proportions may be slightly varied within the usual limits without departing from myl invention. The base sections are of such shape and proportions that they may be easily rolled in an ordinary. rolling mill and thus produced without properly perforated to receive the tie bolts, these sections ready to be laid upon the road bed and secured thereon as may be desired. They may, 'il' desired, be made of cheaper/*metal than are the tread sections which are alone subjected to being worn or damaged by contact oi the traveling wheels therewith.

The manner ot spacing the periorations through the base and tread sections is peculiar and will be explained hereafter.

l5, B, are the tread sections. These are simple in form and easily produced in a rolling mill as will-be apparent from an inspection oi their cross sections. They are cut square across and provided eaclrwith a depending ilange or web, c, havimng inclined sides and formed to fit in the space between the webs, b, b, of the base section, plane, square shoulders, as at d, d, being formed near the top of the web c and.below the upper part oi the tread section to rest upon the correspondingly liat upper faces of the webs b, b. The up per part of the tread sections may be of any oi the approved forms ior the corresponding portion of Ordinary railway rails. y

In the manufacture o the two portions Oi the completed rail, the lengths o the base sections and the tread'sections are prel'erably uniform, and the tread sections are located in the base sections so as to extend about equally on each side of the joints between said base sections. Thus the parts oi the rail are made to break joints l' perfectly., and when they are finally bolted to place, thc improved rail is quite as rigid and secure at all points as if made in a single piece, and this throughout the entire length oi' the construction.

(l, V(l, are the tie bolts passing through irom one side to the other and being tightened by nuts on one endv .which may be locked by any preferred means. To receive these tie bolts, the two webs b, b, and `the web c are suitably perforated, as indicated. The perforations are spaced at equal distances from each other, the end periorations being locatedat a distance from the adjacent ends oi the section equalgto one-haii the .distance between two ot the perioratiohs. For example, if the holes are spaced two ieet apart, those at the Being so produced and The distance beends are each one foot removed from the ends; and this is the preferred manner of locating them, but the measured distance between them may .be slightly varied without departing from the invention. The passages for the bolts through one of the parts are made slightly larger in diameter than the bolt to allow fdr expansion and contraction under the effects of heat or cold. The larger passages may be made through either part as may be preferred. In the example shown in Fig. 3 the larger passage is formed in the flange c, as at e.

When the parts are in place and the bolts tightened up, the flange c is firmly pinched between the webs b, b, and the tread section B is rigidly held in its position in connection with the base section. this union is made equally at all points of the rail, as will be apparent from the uniform distribution of the tie bolts.

' holes properly punched through the'flange c and suitably spaced. Thus nit will be apparent that the improved rail may be easily repaired upon the road as all the joints are of extreme simplicity.

As will be seen, the flange c does not extend to the bottom of the space between the two webs b, b, thus leaving a chamber below the flange c when the latter is The security ofv tread section, the flange c and the Webs b, b, are made A comparatively narrow so that they may be easily rolled in an ordinary rolling mill 'and so. that the necessary stability oi the completed rail will not be impaired.

Being constructed and arranged substantially in aceordance with the foregoing explanationsI the improved rail will be found to admirably answer all the purposes or objects of the invention hereinbeiore alluded to.

Having now fullydescribed my invention7 what I claim as new herein and desire to secure by Letters Patent, iszl The herein described continuous rail comprisingr a plurality of base sections, a plurality of head or tread sections and a series of tie bolts uniformly and equally spaced throughout the length of4 the entire rail, the abutting ends of the tread and base sections being located midway between two tie bolts, the base sections having' each a base flange and two web flanges and the tread sections being each provided with a depending flange, the upper faces of the said web flanges being flat and the depending flanges on the tread sections having flat shoulders located below the upper parts of said depending flanges for bearing 0n said web flanges.

In testimony whereof, l have signed my name to this specification in the presence of two subscribim.'l witnesses.
